Scope of supply

 

The scope of supply of every ekinex

®

 presence detector includes the device, a lens complete with a frame, a 

KNX standard plug for the connection with the KNX bus, and a set of fixing screws. No additionally ordered  
part is required.

 

The ETS application program can be downloaded from the ekinex

®

 website www.ekinex.com.

 

In  case  of  need  (e.g.  for  replacement  of  broken  parts),  the  device  and  the  lens  /  frame  assemblies  can  be 
supplied separately; their codes are listed in the following table.

2.3 

Operation

 

The presence detector reacts to the thermal radiation emitted by moving  bodies. A person that crosses the 
monitored  area  automatically  activates  the  lighting.  As  soon  as  the  sensor  does  no  longer  detect  any 
movement, a delay is started (whose duration is configured through ETS) after which the lighting is switched 
off.

 

If the standby mode is active, the lighting is maintained at a lower brightness level as an orientation light for 
the length of the configured standby time.

 

2.4 

Light intensity measurement

 

The ambient light intensity is measured by an integrated brightness sensor having a linear output profile and 
an additional filter matched to the human visual sensitivity. 

 

The light sensor is capable of sending a binary telegram (On or Off) to signal a light intensity level which is 
higher  or  lower  than  a  configured  threshold  value,  regardless  to  the  operation  mode.  The  measured 
brightness level in Lux units can further be transmitted on the KNX bus.

 

2.5 

Lighting channel

 

Two operating modes can be chosen for the lighting channel during the configuration phase:

 

•

 

fully automatic

 

•

 

semi

-

automatic

 

The  fully  automatic  mode  has  three  different  states,  i.e. 

ready

, 

active

  and 

passive

,  whereas  the  semi

-

automatic mode only has the 

ready

 and 

active

 states. In semi

-

automatic mode, the lighting is not activated 

after the detection of a movement, but only after pressing an external pushbutton.

 

2.6 

HVAC Channel

 

The HVAC channel has the same operating modes and communication objects as the lighting channel; the 
detection  of  movement  and  presence  is  enhanced  though,  introducing  the  “long  duration”  principle.  The 
detection is based on several time windows (from 2 up to 20) of equal width; in every one of these windows 
at least one movement must be detected in order to yield a positive response.
